It depends on a number of things. Condition, location, perceived value in the market place.

I purchased a Brunswick Anniversary from ebay 2 years ago and I paid $2000. I then had to move it myself.

There are a number of used table vendors that post on ebay. You may wish to search for Brunswick Pool Tables on there and see what's going. When you find a listing by one of them, shoot an email and see what you can find out. Good luck!
